I have an Aquaclear 10 bubbler I no longer need, and I'm hoping to trade it for a heater with programmable thermostat. I keep shrimp, so I need a heater I can set to a lower temp, but have just in case.

Also, I have a Tetrafauna Reptofilter I no longer need as well as the gravel I used to have in my shrimp tank. I switched to sand.
